You do not need the ‘Nav’ model but it must have the larger screen, not the little one.
Just to add to your check list:
Roof rubbing on roll hoops.
Gear box operation/noises.
Delamination of centre screen.
Yes, the delamination appears like spider cracks in the corners of the headunit screen.
Where the roof is lowered down behind the roll hoops the two can come into contact with each other, look for scratches on the back of the roll hoops and damage to the leading edge of the roof (assuming its a soft top given your budget).
Like i say, it would be worth getting in touch with Paul Roddison to see what cars he has or will have coming in, he tends to have good value for money cars for those not looking to spend retail money.
At a franchised dealer the newest that £10K will get you is 10 years old.
As suggested by others give Paul a call. At that sort of budget you’re better relying on aftermarket specialists to service and rectify any problems that do arise.
I understand that this one was the ‘base’ 1.5 model with the ‘small screen’. I think you are going to struggle to get what you want without upping your budget.
I think if comes down to to, I would rather find some more money. I ended up comprising when I bought my NB and it always bothered me. Also being a lot older now, I guess this is my last ICE car so I may as well wait
