I think a tad too much.
I am curious….. the car in your original post, are you selling or buying ? The Gumtree car, selling or buying ?
Personally, I agree with 'someguy360' …. modifications are a personal taste, what you think is terrific, will be somebody-else’s terrible.
If I was buying one now, it would have to be original, the least kms shown, and less than $35K. Then think about if you really want/need outlandish wheels , lowered suspension and whatever engine mods. Your taste, your choice, your $$$$, but resale at a later date will be compromised..
I bought mine new, and it is still as was, apart from 135Km, CV8R wheels and all new bushes in the front, so I have a biased opinion..
