Most car dealers will offer a mechanical inspection. Some will make a big deal out of how many checks they make, but it's important to note that a 120-point check isn't necessarily better than just a 60-point one - it's the scope of what they're checking that really matters. A good car retailer will sell the car with a 6-12 month warranty. If they don't, you can hold them liable for any major faults that develop within the first six months - that's because the faults are deemed developing or present at the time of sale.

The key to finding a good extended warranty is found in the list of inclusions and exclusions. A warranty that excludes most of the major mechanical parts will leave you with lots of expensive bills. For our extended warranty guide, see: www.honestjohn.co.uk/cheap-car-warranties
