Two things drive prices for them – restoration costs and survival rates. Professional restoration, including buying one in the first place, will easily cost more than £25k. Even restored at home it will be north of £15k.

Survival rates are low because these were workhorses and didn’t start getting admired and cherished until the Nineties, by which time the majority had been scrapped. There’s every possibility that prices will carry on climbing.

Spend on my IS200?

I own a 2001 Lexus IS200 which is in fair but not perfect condition with 80k miles and two previous owners. Is it worth tidying up before selling, considering I snapped it up five years ago for a grand? It really just needs the wheels refurbished, some paint correction and a bit of rust sorted on the rear wheelarches.

If you’re asking if your Lexus is200 is collectible yet, the answer is no. Very small mileage 200s will be worth keeping, but high milers less so. Sounds like you bought it well so it’s worth tidying it up and seeing if you can get your money back. I’ll be impressed if you’ve had five years with a Lexus and zero depreciation. Quentin Willson

Keep or sell my Audi TT?

I have a May 2006 run-out TT MKI convertible with full service history, two owners and warranted 51,000 miles in special order Asus Silver. It’s two-wheel drive and has the more powerful 163bhp 1.8T engine. How much is it currently worth and should I hold onto it? Rob Laughton.

The low mileage on your TT roadster is definitely in its favour but most buyers looking to keep these cars for the future want the higher-specification 4wd and V6s.

I think in a retail sale your TT might be worth around £4000. But it’s not likely to increase in value in the short term.

I hope this helps. Quentin Willson
