I’m 20 years old and need a hatchback with a powerful diesel with the idea being that I will be able to pull a small trailer with a superkart on it. My absolute maximum budget is £4000 and I’ve found some decent looking 1.9 TDI Cupra or FR models for that price. Only thing is the mileage. I know that the engines are good and that if looked after a diesel will run forever. So basically, what should I look out for on an 03-05 Leon with 80,000+ miles on the clock apart from the obligatory FSH? Any parts in particular that should have been changed by this point?

Any help or tips would be much appreciated!
