Wow, can you explain to me how you ever got a dealership to consent to this initially? Did you just do a ton of work on one car for free and they saw the difference in the price they were able to bring, retail or at auction?
The dealers that I've ran into seem to only care about price, usually they'll pay around $100 for an interior, plus clay bar & aio on the ext (~3 hours), which is why I refuse to do business with them.
You said that you work another job, is this detailing for another segment of the market, or something different entirely? With the money that you're getting for your work I would look to expand and hire employees if there's enough demand for your services.
I am considering expanding, but I am nervous that if I hire & train the right guy, they will get poached by one of the 2 detailers in town.
What happened was about 3 years ago, I had family with a small used dealership. They asked me to buff a car that hadn't sold at auction for over a month, it was an AMG Kompressor CL55 that had a salvage title, they took it on trade. It was a solid car, rebuilt well, couldn't tell anything happened. However it was grey in color from all the swirls, I did a 3 stage on it and unearthed the excellent black paint job it received. It wouldn't ring the bell for 12 grand with low miles. The first trip back to the auction it sold for 15k. I did this with a few other cars and my family was actually buying trade-ins from other dealers that were run at auction and came back, I'd buff them back to life and right back to auction they'd go. Whenever business was slow, they'd buy up trade ins and make their income at auction.
They eventually tired of the business and took some personal time and sold their lot.
I literally walked in to the largest dealership locally and offered my services for one time free. I asked the GM to see what his 'detailed' cars looked like, explained how I could make them look 10x better and asked who was doing their work & what the rate was. Local detailers did an inside and outside service for $130-150, this was vacuuming, dusting, spraying some juice, washing the outside, clean the wheels, glaze & wax. The GM specifically said "every car looks like $#&!!! A couple days later" and that's when I insisted he let me do a car, the right way, for free, run it at auction and see what happens. He said the auctions offer detailing services, but it's a quick detail and it's expensive. He wouldn't give me a price. I did the first car for free and that was all she wrote. They scored on the first car and since then, they've opened up their wholesale parking lot and we literally walk inside, grab a dealer plate and drive as many cars as we can a day, back to our shop. We pick which cars 90% of the time, and we decide what gets done to them the vast majority of the time. A couple times a week he will say "just clean the inside good and wax it". Nearly every car I'm doing is getting at least a swirl removing/improving polish and 3-4 a week are getting a multiple stage buff.
You're not just a sub contracted car cleaner for dealerships. You have a lot more worth than you'd realize to these guys if you can convince them to let you show them how you can resurrect a violated paint job. Do you realize how many good running cars look like they were washed with rocks and look like total trash that dealers STEAL on trade? They will look you in the face and tell you the paint is ruined and there is no way they can retail it, so it's going to auction to 'lose' money or break even. You have to remember that NEW car dealers are a large business, if they are subbing out detailing - they have money. Lots of it. What is $1500-$2000 a week to them sending cars to you, when they are getting an extra 500+ each car at auction after you work your magic? What is 1500-2000 to them when you resurrect a car they stole and they score a 1500 dollar profit on one car, and got 500+ more than usual for each car? Have you ever seen an auction inspection prior to being on the block? Almost the ENTIRE inspection report is based on the condition of the paint.
I did a silver Porsche SUV this week, it was covered in tar, obviously been slammed through a car wash on a regular basis and scraped clean of snow and ice with a brush multiple times. This DIFFERENT Dealer (new client) stole it on trade, asked if we could clean it up, I told him I'd make him puke when it was done. My crew did the interior in 3 hours and I spent 7 on the outside, 2 stage, CG glaze, with Griot Spray wax for $175. Super deal for him. He wholesale'd it to another dealer, called me up to say thanks for the great job and bragged about his profit, then sent us 6 cars, 3 that he requested a 2-3 stage at my normal rate ($100 to turn machines on and $50hr following). One vehicle he sent me was a Lincoln MKZ with 96,000 miles, black, with a passenger door that the clear is peeling off - he asked for a 3 stage buff, he's having the door re-cleared, instead of just sending it to auction as is, taking a bath on the trade - it's covered in swirls and scratches but it'll come out - he'll spend 200 to have it recleared, his investment will be about 600 total and now he has a presentable car to retail. I told him the buffing will run 200-400 on most and he said that's fine. Then the dealer he sold the Porsche to, sent me 2 cars after the referral for polishing.
Walk in and show these guys what you're capable of doing. They've been getting the cheap, AIO or glaze finishes that honestly don't look good or great. They don't understand that you can make many cars look like they just left the factory.
