Most RC drifters are just as proud of their bodycraft as they are their skills at the wheel. Thats why most want to do their own shells. However Im sure that you can convince someone to do a shell for you. I also know that HPI has a good selection of prepainted shells. Maybe one of them will suit you.
this is the site i use for nice drifters they are expensive but come with everything you need to look the part. wing, mirrors, wipers, mufflers etc only problem i may have once i order is the pre drilled body post holes may not line up with my sprint 2 but i will figure something out anyways here you go check them out.
