Depends on your back really. I find that i adjust mine occasinally as it helps supprt my back depending whether i've been tense at the office or working hard at the gym. It also helps on long journeys almost acting like a massage
Before getting my car I had an S-line for a weekend demo, then an S3 for an afternoon, neither had electric lumbar support and I could never quite get comfortbale - lower back was never quite comfortable.
I specced it with mine, and have got it set right for me, but obviously never adjusted since then. So, get a test drive in one without elec lumbar, an extended drive if you can - if you get comfy - no need, if you can't it's a worthy addition!
personal opinion but I would say YES as I find the base backrest in the A3 soft. I missed it off my 3.2 ages ago and I have to say the S3 seat is much better. It is true that you probably wont change it but that doesnt make it not worth having..
depends how old you are or how bad your back is - im old but didn't spec it but now thinking like you - is it worth having - im going to see if my local audi has one and try it - it wont be a perfect test but I just add it anyway - may do the same for the load through option was thinking of colour coding the wing mirrors but I may keep them silver anyway
I did think about electric seats but every seat ive tried is frustratingly slow - sure memory seats are better but ill probably stick with manual unless someone can sell me the benefit other than sheer laziness
decisions decisions - so indecisive - lol on the same day I spent >7 times the amount on a new flat to rent out and spent about approx. 1/700th time deciding whether to buy it compared to a replacement or new car, crazy really - cars really do hit that emotional button
is it me or are audi and other manufacturers missing a trick - seems that a lot of options you have to specify as part of the build and retro fit isn't possible. surely you should be able to buy any option after getting the car and to avoid people having a low spec just make retro fit a lot more expensive
ive read some comments that if you don't specify electric lumbar support you cant add it later as the electrics are different - crazy, what a missed sales opportunity
