Upgrade or new bike

Hi
I have a Trek 1.5 which cost £700 2 years ago. Its been great, but now thinking of upgrades. Thinking upgrades may be better value than buying a new bike at some point in the possible far distant future when I have a spare ca. £1200-1400.
Trek 1.5 currently has Alpha 100 al frame and Tiagra
On Wiggle can get 105 Group set for £300 and Zonda wheelset for £400
So £700 to upgrade both wheels and Groupset, vs say, £1200-1400 for a new bike
Any thoughts? Is £400 on a wheelset really going to gain me much over the stock Bontrager wheels? Also upgrading means I would still be stuck with the alpha 100 frame - is that so bad?
Thanks

But ultimately the bicycle is a composite. Wheels and components swap around. Buying second hand can give you much better value for money, but that also extends to complete bikes - you may get more for your money by buying a complete bike, but you have a choice between good old (and depreciated), and paying full value.
With the above in mind, I'd suggest you spend your money on some good wheels, and upgrade your components on the cheap (including sales), unless all you want is a slightly flashier bike.

Get a new one *&* upgrade the old one.
The new bike will have cr4p wheels on it so so can put the ones you buy now on as soon as you get it.
I would not bother with changing groupset. Put the money towards a new bike.
Getting new wheels might give a performance improvement, but could also reduce reliability if the new wheels are 'too' lightweight.
I'd start by looking at what tires (and inner tubes) you are currently using. Changing to lighter weight tires and tubs can make a noticeable difference at fairly low cost.
If the current tires are 'wire bead', then simply switching to 'foldable' will reduce the weight. But make sure the rims have the inside 'hooks' to grab onto the bead of the tire - it would be unusual if they didn't.
A problem with doing piecemeal 'upgrades' is that you then have a bunch of used parts that can be difficult to sell, and aren't of any use to you.

Yes the wheelset is certainly worth the money as the stock Bonrager wheels are shoot. But you would still be stuck with the same alu frame and if you're going to be spending you might as well go carbon.
Personally I would say keep the 1.5 as a winter bike and get something like this http://www.planetx.co.uk/i/q/CBPXRT58RI ... co-edition
