Type of purchase MX 5 NB(110 ps)

Hello since I have long been looking for a sporty car with low maintenance costs I have come across the MX 5. Whether maintenance costs in themselves (insurance, usage, tax) or repairability, everything seems to be given. Driving fun I think also comes up with the smaller engine. Now to my “headache”. Unfortunately the MX 5 seems to have enormous rust problems. When I hear that most fenders/swings are through and it sounds more like lotto to you without rust. I think it is realistic to calculate 1000€ for welding work with its own preparation. To this purchase price 2500-300€. What do you think? isn’t it so dramatic? Would also be interesting as the spare parts supply is, so price-wise. MFG
