I've spent several months agonising over this question, to the extent of viewing, test-driving and, in one case (and annoyingly for the seller, no doubt) putting down a deposit on a 997.2 GT3 on the Friday morning only to ask for it back on the Friday afternoon. The conclusions I came to were:
- GT3s were looking over-valued and I thought they might pop.
- If they kept going up in price, I'd be less willing to drive and enjoy it (an issue I have begun to feel with the CSL, in fairness).
- To enjoy the car properly, I'd need to be able to take the family on road trips or it would have to be purely a toy, and would get driven perhaps once a month or so.
I ended up buying a stage 4 GTR with lots of toys from Litchfield for just over half the price of the GT3 I was looking at. Although it's a nice car and will not lose money hand over fist, it's no GT3 in engineering terms and I don't feel that I need to treat it with kid gloves. It's practical for the family, I put the miles on it if I feel like it and, in performance terms (with the LM suspension especially), it would brutalise a GT3 in most circumstances.
BUT
The GT3 is still more desirable and this thread just made me look again at 997.2 GT3 prices. Save for one example, I think I would have made an easy £10k if I had have bought the one I looked at 6 months ago. Tellingly, JZM have hardly any at all for sale, and if there were any out there, they would have them. Oh well, you win some...
