I’ve just bought a Duster after my Focus died, I gave them £7400 and the Focus (which was so bad it barely made it to the dealer).
The plan is to keep it for as long as possible. It’s definitly a cheap build, the interior isn’t up to much but I consider it’s like buying bike kit from Aldi, it does the job for commuting. If it does fall apart I wouldn’t worry anyway as I don’t really care about cars much, so long as it starts and stops OK will do me. It hasn’t got a lot of power but living in the crowded south east you can only go as fast as the car in front of you anyway.
If I were doing a lot of miles I may have bought something else, I only do around 8-10k a year though. 2nd hand cars around that price were a few years old, this way I haven’t got to worry about it as it’s gauranteed and no MOT’s for 3 years. I think that the engine and gearbox in mine is from a Megane, on the Sandero I think it’s from a Clio, so spares should be readily available. If not then I haven’t gambled that much dosh.
If I’d spent 20k on a new car it would probably lose the value of my one as soon as I took it out of the showroom!
