In theory yes (and it's what I have), but does mean double tax, insurance and MOT costs, plus somewhere to keep 2 cars. Unless someone's going full on and trying to win concours trophies I really can't see the need to go to the 'n'th degree with detailing undersides tbh. You can get a chassis and associated components looking clean, neat and tidy without going to a level that then renders the car undrivable outside of show use.
