Cold Car Troubles
First thing in the morning its taking too long for my car to warm up. And it doesnt take much before its cold again. And if i dont wait till the temp to rise is a pain to drive. Its slow, and the gears crunch a bit. Anyone else have the same probs?

So how long is too long?
Based on what you've said some of this relates to the engine and some to the gearbox.
In terms of the engine being slow and sluggish until it warms up could be caused by a number of things, but two I'd be thinking of would be the temperature / viscosity of the oil and the expansion of the engine components.
With the engine oil, what rating are you using and have you tried one that has a wider temperature / viscosity range?
With the engine components, until the engine warms up there will be gaps around various items, such as the piston rings and the chamber wall. Until the metal expands and these gaps are sealed there will be a loss of pressure for each compression thereby reducing power. You could get your rings / pistons redone, but a cheaper option is to just let your car warm up.
One method to get your engine up to temperature faster would be to put a higher pressure radiator cap on. Although you want to make sure your cooling system is in good nic or you could have an unfortunate situation, like somebody else did on this forum.
A car will warm up faster under load (driving) than it will idling, but whatever you do don't rev it hard until it has warmed up as that is when the most damage occurs.
In relation to the crunching gears, you might want to do a search as a few people have overcome that issue by changing their gearbox oil.
