DSM are far from reliable lol as just about anyone who has had one I can almost guarantee has had to do some hefty repairs. I'm not so sure about the newer cars but the older cars were junk but they can be made to be pretty quick but not reliable. Theres two 2 brothers around here that both have one. Outside appears stock but the motors are far from it pushing 400hp+ but they're constantly breaking so they have other cars like 64 Impala and a Steeda Mustang that they drive mostly.
