Welcome back! Haven’t seen you here in a handful of years. Your car is looking fabulous as ever.My cars now 9 years old. I barely drive it. Other than a yearly oil change I’ve done nothing. I’ve gotta change my battery for sure this year. But I’ve been thinking that maybe I need to change my trans and diff fluids due to age? View attachment 235677
Other than oil, I’d do a coolant flush/fill in both systems. That should be all your car needs right now.
