Bullet Proof Reliability - Incredible Performance

readmore,04/21/2012

What we want in a car is a little like the work we what from our car mechanic, i.e. - Fast & Cheap & Good. The trouble is... you only get to pick two because the holy trinity of all three is as elusive as a Powerball Jackpot. So what most of us look for in a car is a balance between the car world's current holy trinity of Performance & Reliability & Fuel Economy. I believe that this is

Good Stuff Cheap

I just bought an '03 Q45 in pristine condition. The luxury options on this car are more than generous. The power of the engine is amazing too.

This generation Q45 is attractive and comparably equipped as the likes other Asian and Euro vehicles within this "new" price segment.

After driving my 1997 Touring edition for over 168,000 miles with no major repairs needed, I was looking for a newer replacement.

Should I lease or buy a 2003 INFINITI Q45?

Is it better to lease or buy a car? Ask most people and they'll probably tell you that car buying is the way to go. And from a financial perspective, it's true, provided you're willing to make higher monthly payments, pay off the loan in full and keep the car for a few years. Leasing, on the other hand, can be a less expensive option on a month-to-month basis. It's also good if you're someone who likes to drive a new car every three years or so.
