I reckon the trick to getting your mrs to be quiet is pretty simple, just mod her car first then she cant complain when you take your turn to mod yours (your being the more expensive to mod
)
case in point, my mrs had a 1.4 polo.
i bought her a 2ltrT EOS, remapped it, new zorst, CAI, 19" rims, full leather, and a stonking bodykit.....ended up looking like this:
this now give me access to mods for mine without any winging.
when i bought my 19's....which were vastly more expensive...she cant say a word
and anyway......you only need to make them aware of the mods they notice...theres alot you can do to a car without them noticing
that is unless they read the same forums you post on
