Well, I'd have to go with some 'elbow grease' upgrades starting with wheels. I've seen trucks with old/dirty rims and no hubcaps suddenly 'jump' in appearance just by cleaning, sanding and respraying the rims white and adding some quick chrome poverty caps.
The next would be cleaning and detailing under the hood and cleaning the interior including adding a seat cover.
Costs for the above are almost nill.
All Good
