I say if you wanna stay auto, do it. My project car at this stage may end up staying auto, it seems its gonna be a stuff'a'round to change it over due to the auto crossmember and manual crossmember not lining up.
Plus its something different, a more relaxing drive, not having to worry about changing gears.
Do what you want to your car cause in the end, its your car and your the one who has to drive it. Do what makes you feel comfortable.
Some people criticise me about my choice of putting Venetians in my car, i just shrug it off cause its the look I'm after.
Don't let any ones negative comments change your mind.
Peace out,
Jon.
