Would like a Knowledgeable opinion…

Hello,

I am a returning player I have about 15k battles but have not played for a fair while. Totally out of it as far as the game goes.
I have 6 Girls Not yet recruited and the following vehicles unlocked ready to buy during the discount;

1. Tiger I

2. SPIC

3. VK3001p

4. VK3002d

5. Panther II

6. Skill book for ELC amx crew.

7. Start the Japan Medium line….

I have enough spare XP to upgrade any of the above from stock.
I like mobile and nimble vehicles that are fun to play would also like to cause some damage, but I am open to suggestions.

Any recommendations folks? Thanks.
