3 Car Garage

Well it's finally going to happen, I am selling my current house with a 2 car integral garage and buying another home 15 miles from where I currently live, the only problem is that this house doesn't have any garage. So here's the good part I get to build my own 3 car garage Woo Hoo! I have been waiting for this forever, now here's the question, I am trying to keep the cost to a minimum so I can't build a monster size garage, do you guys think that 24 x 32 is big enough to work in? Also will 10 ft walls with the tresses modified be tall enough for a lift? Thanks for your input, pictures to come when construction starts.
