A series 3 is a good choice if you want a work horse that doesnt require a degree in mechanical and electrical engineering. The parts are cheap and they are easy to fix. a long wheel base give most flexibility for carrying loads, the downside is the turning circle is a pain especially for tight parking. The two main things to look for a good chassis and a good bulkhead. If you can get one with a galvenised chassis, so much the better. Series hold their value wdll and if you buy the right one, a little work on it will make it an investment. Petrol is the best in my opinion, quieter and quicker but the fuel economy isnt great, I get about 17 to 20 mpg out of my 109 station wagon. Im 6ft 3 and I fit in it ok but the driving position (bolt upright) gets a bit of getting used to. Make sure you test drive an potential purchase, neglected ones suffer from poor steering and brakes. Having said that, the brakes and steering arent great compared to a.modern car but the do offer a unique driving experience. Try not to buy a ringer.
