I concur with the answers above regarding the roof fitment and sound deadening.

Regarding the 20 HP difference between an 07 220 and 08 240; I doubt you will notice it during regular driving. What is more noticable is the quality upgrades. There are some features between the 2 which you may find better/worse - depending on your perspective. For example, the 08 240 has larger brakes. These brakes are overkill for the street - they can make a noise and be hard to be gentle with - they like to grip and stop. I have had a hard time transitioning to them but think I am getting the hang of it. If you are not used to 07 and earlier brakes - you may have less to overcome than me and not be aware of the difference - but the new brakes are a little excessive for street use in my opinion. The shifter is also better in the 08 and overall the car will seem tighter. Lotus did some kind of quality enhancements which were relatively minor but seem to have a big payoff in feel. Again if you aren't accusomed to 07 and earlier, you may not notice this.

I have had a 06 Exige and went to an 07 Exige S - there was a noticable power difference and the dynamics of the two engines are entirely different. I have now gone from an 07 Exige S to an 09 Sport 260. I notice the difference in power (roughly 38) and less weight. It's something different alright. I cant say I noticed a power difference between an 07 and an 08 - especially during regular driving conditions. Perhaps on the track it may be evident.

The LSD, I do not think this will help you in inclement weather conditions. In fact, it may hurt you. Lotus uses a different kind of LSD on these cars. My 06 had LSD, My 07 did not and my 09 does. There are many reports of those who have suddenly lost control in rain due to the LSD.
