ASK QUENTIN

Classic Cayman?

I have a 2015 Porsche Cayman flat-six with 22k miles and full service history that I’ve had from new. Is it a potential future classic?

George Nuttall

Like all Porsches, your Cayman is definitely a future classic. But it may be some time before we see prices start to rise significantly. When you carefully work out how much it cost you originally to buy, plus servicing and maintenance and the interest on the money you’ve spent owning it, any notional future gain might be wiped away completely. I wouldn’t worry about the future. Just go out and drive it – now. Quentin Willson Invest in my Astra Bertone?

I own a 2004 Vauxhall Astra Bertone coupé convertible 2.0 turbo with 50k miles in very straight condition although it does have some minor cosmetic issues.

It’s totally original with the five-spoke alloys and original exhaust from new. The car is a joy to drive, apart from the petrol consumption. I’ve noticed these cars seem rare, with similar examples advertised at more than £4000. Before I spend money on cosmetics, is this a potential future collectable?

While the Astra Bertone coupé is rare, I’m not sure it’s a future collectible – not in the short term anyway. Even the more desirable Calibra has struggled to gain market recognition. I would only spend what you need to make it saleable and don’t invest heavily. You might struggle to get your money back. Quentin Willson An Abarth to keep

My wife has a beautiful Abarth 595C flappypaddle nod to Ferrari with 183bhp – it gets looked after like a baby. My wife is 66 years young and she loves the sound and performance. Will this become a future classic? Ian Pickup

Your wife’s Abarth 595 is already a classic and could, in the long term, appreciate. Quentin Willson
