It need a bit of welding underneath and have been quoted £400 as the seats, carpet and fuel tank need too come out.
Are you sure the tank needs to come out ? Where are the holes?
I had to have some welding done to mine this year...
Front drivers side had holes near the crossmember that the seat bolts to.
Rear both sides holes where the rear seat and floor meet.
Not surprising as there are built in holes in the car in the first place !!
I managed to get all 3 patched for £150, although I did strip the interior myself.
I had a big moment of panic when the mot'er said there was rust in the floor, plus a couple
of advisables, almost thought about giving her up...
Then I looked at her, and thought I can spend a couple of hundred pounds on her, and get her back on the road for at least another few years, or struggle to come up with more money to buy another car, which would still need to have money spent every year to keep it on the road.
So off to the welders she went, and now lives to fight another year
