IF you can stick it in the garage and forget about it, then do this. As you say, you know the car and it will be easy to get back out and enjoy if the bug bites. Much easier than deciding to buy another and get it insured etc etc, you just wouldnt bother.

You may find after a year you dont really fancy using it anymore and sell up anyway, but, you drive an rs because you get a buzz from an rs, so may just find you hanker for that rs buzz.
