Agree with the ‘modifying cars’ comments.
IME they can be great fun but not as daily drivers.
My last modded car was a Saab 9000 Carlsson that Abbott Racing had tuned. I loved that car but basically I completely buggered the reliability. Fun while it lasted though!
Rolling road had it with 260hp at the front wheels so was ‘quite pokey’. Sorry Simon… I was young.
Also having said that 260hp isn’t actually that powerful if you look at a typical modern rep mobile. Plenty enough for a H reg Saab though…
