If your looking for investment I'd buy a P1. ..if you can stretch the budget obviously go for a 22b, but a nice unmolested P1 with history left alone will appreciate...I'd even leave on UK reg..although objectively probably not as good a car as the V6 type R the fact they were UK official models means they will be more valuable in the future..they were bottoming out at 5k 2-3 years ago and now some are back up around the 8k mark
