My recommendation would be to keep the 04 eagle eye on first priority over the SE Saloon because of ABS.
if two cars are a priority then choose Nissan as it is only a 4-6 year old car vs. the Dolphin which although very popular is still a 10-12 year old car. Plus usually Nissan owners are Babas, so generally speaking you'll find this particular shape in better maintained condition.
However both these cars will cost over 7, leaving you around 2 from your original budget towards getting a smaller car. You will still have to put in another 2 atleast to get a decent small car in decent condition and that too you will be limited to a Mehran, Alto or a Santro...(not including coure and cultus).
If you add another 2 or 3...then the argument opens as to why not add this same amount in your original budget and go for used XLi in new shape (08) or 06 VTi Oriel in excellent condition or maybe even a belta 1.3...hey you might even get a 05 or 06 altis in that price...
However, sticking to your original budget I would still recommend you a 04 eagle eye (eagle eye came 04 plus) as it is the best package.
