I have spent about £1000, got the car a month or so ago.
It needed a 72,000 mile service, which is expensive anyway, and the cam & accessory belts needed to be changed at the same time. The offside tracking rod end has excessive play and so I had that fixed too.
My Cabasse dash multi changer also packed up (couldn't load CDs) and so I got one off
for £100. Dealer said they would charge £591 for the same unit. Oh I laughed.
I dropped my key card on the floor and that broke the micro switches. I sent my key off to Gary @ Renault Laguna Key Card Repair Keycard
to have it fixed for £20 plus postage. He did a really good job, and saved me some money.
I repaired the lighting on the climate control unit myself. Cost £2 for some solder (already had the iron).
Also got a new alloy wheel cap (56mm wide one) and a new plastic tyre valve cover together for £10.
