Mods?
I wrekon everyone who loves cars goes through spending lots of dollars on mods. Some just don't know why they mod, they just enjoy muckin around and end up spending lots of after tax dollars on a car that they like but to be with the "In-Gang" then try to sell it after they are sick of paying for more and more mods to make it look good, sound, better or go faster. (Wasted money)
As you get older, life seems to take a change; those guys with rusting cars in their garages that they'ed love to do-up but have a mortgage, loans and other crap that prevents them from for-filling their dream car because of lack of time and money eventually have them taken out of the garage and crushed for scrap, which makes the misses happy.
A rare variety, get into racing and just idolize cars, it's their life, a new head or turbo is like a new Shimano game real to a serious Tuna fisherman.
In the end, we get to a factor of realising that the guys who build cars professionally have budgets, targets and limited resources but are highly trained (Technical ability and qualifications)to produce a product that sells cars to the general public. (Common cars)
A few tweaks or mods might get you there quicker but a nice new car that you afford the rego, tyres, Comprehensive Insurance, upkeep the maintenance and the extra fuel so you can enjoy driving with ya mates is what counts.
All us blokes like to compete, it doesn't matter if it's 2 mates with the same mod car but they'll always compete, so there will always be mods. Err, except when ya just don't give a f--- Any more.
