You want a year's MOT on any of these cars. If buying privately, do your research. You can pull previous MOT history via government check. Also speak to owner. Genuine owner will have paperwork and lots of it, plus history. For these sort of vehicles, keep your search area tight. No point travelling for 'immaculate example' only to be disappointed. Always drive a car from cold, and cross reference vehicle VIN on inspection. For a car you're prepared to buy, and given we live in a world where we're surrounded by scammers, then pay for a vehicle report such as carvertical. RAC offer something similar, but less detailed. If you have VCDS, definately scan the car. Diesels on the whole are robust. At this age, its Euro5 technology. Regular oil changes are key to engine longevity. Anything on long service intervals 15-18k intervals, walk away. All 2.0 TDI engines will be belt driven, so again, when was toothed belt done? My advice is 60k miles or every 5 years plus waterpump. If any cars have panoramics, then check carpets, and headlining for water leaks. Test all electrics, central locking, etc. Sat Nav likely out of date, but it is what it is. Scuffed wheel rims, someone can't drive. Alignment will be out and I'll bet it pulls to the kerb. Check coil spring height. Easy test with your hand on level ground from tyre to arch.
