I'm new to T25s and to the forum so please bear with me if the pics don't come through first time. Many thanks in advance to those who read this and those who help.
I'm looking to buy my first T25 and have been to view a likely candidate. It's A Reg, and has just come through an MOT last week with no advisories. However, there's this patch of rust and a hole in the underside that made me stop and think.


It's just forward of the nearside rear wheel and the pipe you can see is the sink overflow (or so i was told). So please correct if I'm wrong but it appears to a hole in the chassis just in front of the strut that connects the rear axle to the chassis (I am certainly no mechanic, so forgive me if the terminology is incorrect). I took a T25-owner friend with me, he was an invaluable source of advice and spotted the hole but he's not a mechanic or welder. He advised me to take some advice before purchasing.
So is this a structural area? Should this have been mentioned as an advisory on the MOT? I guess I'm a touch suspicious (this might not be my best attribute but it could save me some money!)...
How much might this cost to get repaired and how soon might it need to be done?
I hope there's enough info to go on here, and I'd really appreciate any advice that anyone can offer me. Thanks in advance.
