Friul tracks are always a nice replacement and much easier to deal with.
Never be tempted to rush these kind of kits as they are expensive and have loads of parts in them.
You will spend more time in the paint booth. putting it together is the least worry and you should spend lots of time with the kit and instructions getting yourself familiar with the parts and the build. Always have a good idea on how you want the finished kit to look before you start.
I'll be adding the Takom Panthers to my stash over the next few months.
I don't know which one you have so at the moment it is not easy to tell you what I wold use, but here's Meng's Panther A - It doesn't have an interior, but you can follow my Meng Tiger II build which will give you a very good idea about the interior of German Panzers
I use Vallejo model air as they are one of the few companies that don't subscribe to the scale correct colour thinking so their colours are absolutly original Chip correct.
As an instance, here is an original colour made for me by an actual OEM Wehmacht supplier who is still supplying the German forces and was remade from their archive for my real full size tanks and is the shade for a late Panther A base coat. On the right is the supposed AK "Real Colour"
There is a huge descrepancy between 3 of the 4 shades of RAL 7028 which were used and the Dunkelgelb Nach Muster is close. That colour was only used from February 1943 until the end of OPeration Citadel in August that year and then it changed.
Interior colours also changed... but that's a different story.
First things first. look at how the kit is designed and then work out how you want to dispplay the finished thing. Work backwards from that brfore you start. Have a build plan in mind all the time.
Also google Panzer V Panther in interiors and exteriors. Don't go by colours or try and match colours to black and white photographs. Just look at the detail on the vehicle and where the colours change. These things were constantly being upgraded and so things would be different from tank to tank
