I would be very cautious with both of these.
The Brooklands smells wrong to me. If you look at the written description in the ad it talks about £38K.Plus this add has been around a while now.I am sure something genuine at this price would have been snapped up in seconds.
The Yellow £25k car has been on sale with same company since July 2023.It is an early very year with low milage example that has been sat in a garage. It has no information that suggests any of the usual fixes have been performed, therefore could end up being more expensive than an average £36K example.
