I need an estate car. I play around with old cars such as Rover P4s, Triumph Spitfires and the Land Rover series. I considered that a Rover 75 (except the 1.8) would be a good fit, however the ones I have seen are expensive and with high miles. I thought about a Mercedes-Benz W123 estate (I am told to avoid the 280 and any with a sunroof, with leaks causing rust) but I know nothing about the W123s except that they appear to be a good thing. I toyed with buying a Peugeot 406 3-litre executive with 45,000 miles and in mint condition, however it's not a classic and will be heavy on fuel. Please give me your opinion.
