Given the price of tickets to Dundee, you could settle for a bus through to Edinburgh and then take the Megabus from there. It might be marginally too, given the Dundee megabus goes through Glasgow.
I used to do the overnight run down to Manchester on a regular basis. Leave about midnight, get in about 9:30am. Cheap, but not to be recommended if you can afford otherwise.
If you don't mind spending a few more pounds, get the bus through to Edinburgh, get the train down to Manchester/Birmingham or thereabouts, then get the Megabus/National Express bus in from there. It'll be a hell of a lot more comfortable and probably considerably quicker too. Advance tickets, especially with a railcard, come cheaper than you might expect.
Petrol for a car down to London would be about £60 alone. Not really worth it!
...then again, that is only my opinion.
