I agree with Harris. When i bought my saff i didnt have a lot of money. I just replaced parts as and when the car needed it. I wouldnt worry about the running gear its the body you wanna think about.
Ive used mine for the past 3 months monday to friday and ive enjoyed every minute of it. Ive only used it cause im still waiting for a V5 for the st170 lol.
I used to use the car in all weathers its just the shity winter with the salty roads that i used to hate cause i didnt want the body to rust lol.
By one if you don't like it you can always get your money back.
