If money is an issue, you could always concentrate more on keeping the car in tip top condition instead of adding mods
Good quality car wash
Clay Bar and spray
Cleaner
Enhancer
Polish
Glaze
Sealer
quick detailer
Glass polish
Trim / tyre finish
wheel cleaner and wax
Perhaps go for a set combined with a DA Polisher?
The initial spend goes along way and a standard looking clean car can command huge respect in its own right
I was lucky and got a few bits for my birthday:
DAS-6 DA polisher complete with sonus kit, enhancer, swirl remover, final finish, pads for each, 2 detail brushes, 1 alloy wheel brush, 5 litres Glaze, 5 litres Bilberry wheel cleaner, 5 rolls blue tape, set of micro fibre towels, Gold Class shampoo and an air freshener
Spent a day on my neighbours car and the results are fantastic
highly recommend the products.

The good thing with cleaning is its mainly your own time so not huge expense.
