I don't think the cars you use have an age limit or age conditions, young or old, riding your car is about your personal desire & how you prefer it.
A manual drive beat-em-up like a 1993-2001 Honda accord or 2002-2005 Civic for under for under 5k and drive it to the ground. Or a recent Honda Fit.
I would suggest a hearse , as everyone will want to be taken out in that great vehicle, Now for a bonus optional affect, you could have fake or real corpses hanging out the back trust me you'll look radical.
Medium sized, reliable, underpowered and paid for.
