Hello Sarah,
Definitely follow Steve’s sound advice, otherwise you stand a high risk of exchanging this car for another vehicle with unknown faults which are likely to cost around the same funds to fix.
If it were mine, I would be approaching your trusted local garage, listing the items you wish them to inspect, and asking for a quote to carryout the work. You have to be confident with the outcome of their inspection.
It really is that simple. If you follow the route of ‘only just looking at other available vehicles’, you are highly likely to fall in love with something, and being informed that it will carry a comprehensive warranty, so there won’t be any thing to worry about! Well not until you find out what the limitations of that warranty are.
Just find yourself a recommended local garage where you can actually talk to the mechanics ( very important) rather than talking to Service Receptionists.
Kind regards,
Gareth.
