I've always targeted the general category of special interest vehicles or S.I.V.s.
I tend to like classics more than modern cars for a number of reasons one of them being classics tend to have chrome and stainless steel trim instead of plastic trim making them a lot more fun to buff out. I also like the body lines and body panels better as they have enduring style.
The owners of special interest cars tend to appreciate their cars a lot and after educating them on the topics of both paint and how to work on paint, they tend to appreciate the work that'd performed.
A special interest car doesn't have to be old to qualify as SIV, a good rule of thumb is any car parked in a parking lot that makes you do a double-take, or even better, go off your normal path of travel to take a look at it qualifies as a special interest car.
I think a person is better in the long run to find a niche market and specialize and cater to it. One thing for sure, if you enjoy a specific niche in the market then you'll enjoy your work more...
