You'll never properly align your car in your driveway. The only adjustment you would be able to measure is toe. To do that you would use a tape measure which is nowhere near as accurate a computerized alignment machine, (I've confirmed this, differances of 1/8" to 7/16"), not to mention that you'll have no way of measuring camber or caster. Your only option and best bet is to dish out $60 and have it done right.
