There's no real price guide for a car this age with such low mileage as it's such a rarity. It's worth checking in the classifieds like Auto Trader to see if there's anything similar, so you can judge the price. The 190E is becoming a rare sight on the roads now, especially a well-cared-for one, so it could be a good investment if you don't intend to put lots of miles on it. We think about £3000 is a good price - maybe up to £3100. Fuel consumption will be in the late 20s.
