Attached to my old car, should i sell?

hi ive been trying to decide what i should do about my old car, its a Ford escort 84 sedan, i bought it in 1999 ,pay 500 bucks for it which isnt that much, but its still going and i ive had hardly any trouble her, thus spending money on her..recently i got pulled over by the cops because i was speeding but i blamed it on the car instead of coping a fine of $200, i was ordered by the cops to take it over the pits, but am worried that it will not p because of the age and look of it, it looks like a farm car..but even so im attach to it, its a lil motor but ive spent time fixing her up over the years making her better and mate when she goes she bloody flys..i just payed the rego on it but can return the plates and get a refund..what would u do if u were in my situation, i got a few otehr cars aswell,Nissan R31 Skyline which is a 6cyl, a Mitsubishi Cordia Turbo,and a Mitsubishi Non Turbo,and anotehr small car Mazda 323 which is very similar to my Ford...but the Nissan And Mits need work
