I'm afraid I don't have all the details but it was 2015. I have a receipt from Rennspeed ltd in Gainsborough which includes head gasket etc and clutch kit , so I think it must have been them. There are a load of photos of the process of the rebuild.
Didn’t think a serious petrolhead would be that bothered tbh but have shaken the carpets out now so if you buy her , she will look as smart inside as out.
